Not for marine/water based use These Trackers are mandatory for commercial fishermen in Australia, Queensland. The only waterproof part is the cord, we have had to replace numerous trackers due to just rain and dew let alone salt corrosion. This is why it's a 1 star as it's not suited for the field it's been specified for.

The concept of a Spot device is great, but.... The concept of a Spot device is great. People know where you are, you can send messages and get help if needed. There are several choices available in addition to Spot. I would strongly recommend InReach. From my personal experience there are several reasons. 1. Better messaging 2. Better pricing packages 3. No "ambush" auto renewal billing 4. Better and much more responsive customer service 5. Better user experience (ease of use, set up, reliability).

DO NOT PURCHASE ANYTHING FROM SPOT DO NOT PURCHASE ANYTHING FROM SPOT. They knowingly and purposefully engage in dishonest billing practices. They employ what is known as a "Evergreen Clause" and make it *very difficult* to cancel their subscription services. You will be sorry if you do business with these SOBs..!!

STAY AWAY from this company STAY AWAY from this company! Their device "Spot GPS" does not work most of the time. We've tested it. Despite cancelling my subscription over a year ago, they did the following: 1) Billed my credit card 2) Charged an even higher amount 3) Never sent any notification 4) Never sent any receipt 5) Customer service was slow, they lied, they attempted to gaslight me, and finally begrudgingly refunded my money weeks later ONLY after I reported them for FRAUD to my credit card company. STAY AWAY! THere are better products out there.

SPOT should really change their pricing policies SPOT should really change their pricing policies, the auto renewel without any notice and the increased prices. There is a lack of and unclear communication online and through e-mail. This is so important especially when dealing with international customers where people might be used to different laws and rules. When i found out my credit card was debeted I called and SPOT did refund in the end, gladly. But this is just not the way to go. Also the service itself, i have been on places SPOT couldn't get out a SMS (usually in forests)... Gladly i didn't have to use the SOS service...
